The aim of this study was to construct regression-based norms for 3 executive-function tests: the Trail Making Test, Stroop, and Verbal Fluency.
A sample of 1,034 healthy Icelandic adults (18-64 years) was used to calculate predicted scores for test measures from all 3 tests, controlled for the effects of age, gender, and education, as well as the interaction between these variables.
The 3 demographic variables showed significant effects on most test measures and were included in the final equation for estimating predicted scores. An older age and less education predicted worse cognitive performances in most cases, and women tended to outperform men.
These results highlight the importance of adjusting for age, gender, and educational level when constructing normative data. Controlling for age alone may be insufficient or misleading in clinical-practice settings. A simple, user-friendly program for predicting executive-function test scores is provided.
本研究旨在为 3 项执行功能测试(连线测试、斯特鲁普测试和言语流畅性测试)构建基于回归的常模。
利用 1034 名健康冰岛成年人(18-64 岁)的样本,计算出所有 3 项测试的测试指标的预测得分,这些得分控制了年龄、性别和教育的影响,以及这些变量之间的相互作用。
3 个人口统计学变量对大多数测试指标都有显著影响,并被纳入估计预测得分的最终方程。在大多数情况下,年龄较大和受教育程度较低预示着认知表现较差,而女性往往优于男性。
这些结果强调了在构建常模数据时,调整年龄、性别和教育程度的重要性。仅控制年龄可能在临床实践环境中不够充分或具有误导性。提供了一个简单易用的用于预测执行功能测试得分的程序。
